Tune Belt"s Sport Armband for iPod nano 6G was designed to hold the sixth generation iPod nano WITH or WITHOUT the Nike+ Receiver attached. Features providing unmatched comfort, convenience and protection include: a cord management flap to control and store the earphone cord; a clear protective window cover with full navigational control; a reflective logo for nighttime visibility; and an adjustable flap with two closing positions that covers the entrance when the Nike+ Receiver is not being used and covers the Nike+ Receiver when it is being used and connected to the nano. (To see what the flap looks like, please see the additional images for AB75+ which is similar in concept.) The armband is washable and adjusts to fit arms 9 to 17 inches. For larger arm sizes or to provide extra room to wear the armband over thicker clothing or a jacket, an Armband Extender is available. See model EX3 (sold separately) which increases the maximum arm size by about 6.5 inches. Tune Belt note re product review comments - There are no holes in the armband to access the buttons for volume and sleep / awake. This was done intentionally to prevent moisture from getting into the pocket and the volume and sleep / awake buttons can still be controlled by pushing the button locations through the outside of the case material. Color: Black This item does not include any part of the actual Nike + iPod Sport Kit which is sold separately.
